一、使用场景
某些配置文件里有一些特定的字符，而这些字符恰巧需要我们采集出来，然后输出到另外一个窗口做展示时，可以使用该工具。
本例的演示则提取配置文件中的【姓名：黄蓉 女 九阴真经、姓名：郭靖 男 弹指神功】两行读取出来，读取其他内容也可以，更改相应参数即可。
二、实验文件
测试脚本：fielread.py
配置文件：john.conf
三、测试脚本代码
#! /usr/bin/env python3
# -*- coding:UTF- -*- from tkinter import *
import tkinter ss = input('请输入搜索内容的开始首字符：')
es = input('请输入搜索内容的结束首字符：')
fp = input('请输入要搜索文件的路径：') def fetch(startStr,endStr,filePath):
newLi = []
with open(filePath,'r',encoding='utf-8') as f :
flag = False
for line in f:
if line.strip().startswith(startStr):
flag = True if line.strip().startswith(endStr):
flag = False if flag and line.strip():
newLi.append(line.strip())
return newLi info = fetch(ss,es,fp) # 调用fetch函数进行内容匹配，结果返回列表保存到info中 # []控制台打印输出
result = '\n'.join(info)
print(result) # []alert弹窗打印输出
root = Tk() # 创建窗口对象的背景颜色
new_info = Listbox(root)
for item in info:
new_info.insert(,item)
new_info.pack()
root.mainloop()
四、配置文件内容

# void init()
{
password_length = ; /* Change this to match config */ int c, i; c = ''; i = ; while (c <= '') numbers[i++] = c++;

symbols[i++] = '%'; symbols[i++] = '^'; symbols[i++] = '&'; symbols[i++] = '*';
symbols[i++] = '('; symbols[i++] = ')'; symbols[i++] = '~'; symbols[i++] = '-'; boundaries_charclass[i++] = ; boundaries_charclass[i++] = ;
boundaries_charclass[i++] = ; boundaries_charclass[i++] = ; 姓名：黄蓉 女 九阴真经
姓名：郭靖 男 弹指神功 备注：

boundaries_numbers = boundaries_letters[i++] = ; boundaries_letters[i++] = ;

} # End of john.conf file.
# Keep this comment, and blank line above it, to make sure a john-local.conf
# that does not end with \n is properly loaded.
五、执行效果
Console: 请输入搜索内容的开始首字符：姓名
请输入搜索内容的结束首字符：备注
请输入要搜索文件的路径：./john.conf
姓名：黄蓉 女 九阴真经
